Nothing stable yet. Greenpois0n is going to be getting out very very soon. The good way is to wait one week or so after initial release so most of the bugs that were missed get fixed

I jailbroke my 4.2.1 iphone with redsn0w and it was so bad lol, was tethered mind you.

It froze like once a day and I had to jailbreak it again every time (hence it was tethered)... sucked

u need to have been jailbroken on 4.1 and your shsh blobs saved on cydia servers. since 3.1.3 apple started signing the current firmware release and only the current one. right now downgrading can only happen if you have the shsh blob from the firmware you want to go to and then you need to spoof an apple server

ya jailbreaking 4.2.1 is possible but a lot of the jailbreak programs are still only 4.0 maybe 4.1 ready

If you follow downgrade guides, and successfully finish it, you will end up in recovery. Download recboot to kick you out of recovery and problem solved:)

Hey guys can you help me?!?!?

I used greenpois0n to jailbreak my all new iPod Touch 4g (I LOVE IT) running 4.2.1 but instead of a white screen I keep on getting the "connect to iTunes" image and greenpois0n thinks it has been successfully. Are there any upcoming jailbreaks??? Any news about the untethered redsn0w 0.9.7 that can jailbreak 4.2.1 with no problems?
post #10 of 33
greenpois0n is still tethered as is redsn0w. download redsn0w and check the just boot tethered option (not sure if green has this option as i dont use it to jb) its jailbroken your device just has the new bootloader so your tethered until greenpois0n releases the new version
